OHIP-RECEPTAGLE AND ART OF PRODUCING SAME.

To all whom it may concern Be it known that I, EMORY S. ENSIGN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Chip-Receptacles and Art of Producing Same, of which the following is a specification.

This invention relates to pencil sharpeners, and particularly to chip receptacles therefor.

It has long been proposed to construct a chip receptacle of a pair of spaced framing members with connecting rods, bars, or the like, to render them 'mutually sustaining, and to fit between said framing members, in position to form a side wall of the receptacle, a strip or collar of thin material readily conformable to the outline of the framing members and held in confinement by the flanges thereof. Made first of thin sheet metal with a window at top to permit inspection of the working mechanism, this strip or collar was later made of celluloid to render it transparent throughout. But exposure of the entire area of the wall to transparency is objectionable for several reasons, among which are conspicuousness of unsightly accumulation of chips and graphite dust, eventual abrasion and murky appearance of the celluloid after protracted impingement of the cuttings, and general lack of ornamentation.

The present invention overcomes the objections stated and adds greatly to the ornatmentation and salability of the pencil sharpener by providing upon a part or all, preferably a part, and leaving unobscured the window forming ortion ofthe transparent wall of such a cliip receptacle, a backing sheath of pigment, for example, printers ink, positioned on that part of the area which receives the impingement of the cuttings, and preventing abrasion and dulling of the inner surface of the transparent material, while at the same time rendering non-transparent the-area to which it is applied and showing its color through the transparent wall, backing up and rendering more conspicuous any inscription, design, or ornamental figure placed thereon in advance, and taking on a brilliant surface gloss from the inherent nature of the transparent material, and, withal, eatly enhancing the attractiveness and sa ability of the article.

Specification of Letters Patent. Patentgd Sept. 13, 1921.

Application filed March 14,

1921. Serial No. 452,016.

Fig. 4. is a top plan view of the'form of I receptacle shown in Fig. 2.

1,2, represent the framing members, preferably of sheet metal, constructed with opposed inturned flanges 1*, 2 and spaced apart and connected in mutually sustaining relation by the cross bars 3. Located between these framing members 1, 2, and confined by the flanges 1 2*, thereof, is a wall forming strip or collar 4 of transparent celluloid or the like. Upon the inner surface of all that part of the 00118.1.4; which should be obscured, ornamented, and protected from abrasion, is applied a sheath 5 of pigment,

preferably printers color, that serves the several purposes hereinbefo-re stated. If it is desired to imprint upon the receptacle any letter press matter such as the makers trade-name, the dealersadvertisement, any design or the like, this is done preliminarily to imprinting the sheath, and the latter then serves as a protecting backing, a setting-off background, or color field for such matter.

. I claim: I v

' j 1. A chip receptacle and casing for pencil Sharpeners comprising spaced and mutually sustaining framing members, an intervening strip of wall-forming transparent material sustained between said framing members,

and an obscuring, protecting, and coloring sheath of pigment applied as a backing to, and protecting and rendering non-transparent the bottom and side forming portions of said strip, and receiving its surface gloss from the surface thereof.

2. The improvement in the art of ornamenting and protecting transparent walls of chip receptacles, which consists in impressing thereon, .upon the portion to be protected, a sheath of pigment in position to resist impingement of chips deposited thereinto, and-in position toreflect through the transparent material of the wall andreceive surface loss therefrom.
